Mexican security forces were successful in eliminating Nemesio Oseguera, alias 'El Mencho', the head of the Jalisco New Generation Cartel, during a military operation. Authorities were able to locate him by monitoring the activities of his girlfriend, which led them to surround the area where he was. The encounter escalated when his armed men opened fire on the military, who then responded by killing Oseguera and eight of his associates. Following his death, widespread violence broke out across several states, with armed groups blocking roads and setting buildings ablaze, resulting in the deaths of 25 National Guard members and numerous cartel members.

In a government briefing, Mexico's Defense Minister, Ricardo Treviño, confirmed that a special forces operation led to the confrontation with Oseguera. He sustained injuries during the encounter and ultimately died while being transported to a medical facility. The operation was significant not only for taking down a prominent drug lord but also for sparking a wave of cartel-related violence, illustrating the ongoing challenges faced by Mexican authorities in combating drug trafficking and cartel violence across the nation.

The tracking of 'El Mencho' through his girlfriend underscores the complexities and strategies involved in pursuing high-profile cartel leaders. This operation not only highlights the effectiveness of intelligence in targeting drug lords but also raises concerns over the resulting violence in a country already grappling with severe security issues related to organized crime. The aftermath of Oseguera's death will likely impact the power dynamics within the cartel and the broader landscape of drug trafficking in Mexico, as rival factions vie for control in the wake of his elimination.
